Ceramic Metal Halide Bulbs...for HPS ballasts?

[MaryLane]

I understand!

I guess you haven't got enough time on the CMH to really compare it to the Hortilux.

Whaddya mean 'a mind of their own'? :jointsmile:

Coming up on the end of week #3. Three WW seedlings.

Sorry about no pics. No camera. ...I will try to explain..if this CMH 400 bulb is better than a 400 HPS Hortilux bulb. That will take a lot of doing...because the Hortilux bulb is great.

The plants are doing great...10 inches tall...and a mind of their own...the little shits....:wtf:

...you know how it is...the shortest plant wants to leaf burn...the tallest plant wants to nute burn...the middle plant likes everything just the way it is.....

3 WW plants at the end of week #3. All three plants were 98% root bound in 6 inch pots, so I transplanted them into 10 inch pots, Friday. About 10-12 inches tall, I sniped the top off the tallest one to get them even.

Will start flowering cycle, next Friday. So far, I can tell that the CMH bulb, does NOT throw the heat down, like an HPS bulb does. I can get it much closer to plants; with out leaf burn, IF you wait until week #2 or 3.....enjoy.

Nice update. How is the node spacing?

The real test will come during flowering!

Get a camera ya noob!

No need to wait any longer. One of the plants has already shown it's female pre-flower, 27 days veg from seed sprout! Very bushy, 13 inches tall. Nodes?..if you count them like I do..8-9.

So, 12/12 starts today.

I don't know yet how it will do for flowering...but it's a killer bulb for veg, if you have a 400 HPS magnetic ballast.

I don't usually hand out recommendations, unless I have tried it...at $53 + $10 for shipping...it's a bargain.

Nice, I think, by your posts, you are the same person in the ICMag thread about CMH bulbs.

End of week #1 flowering. 3 WW plants, 2 female, 1 male. All are about 2 feet tall and looking good. (I have 2 bag seed plants trailing along behind; 3rd week of veg for them). It's only been 1 week of flowering; so still too early to compare 400CMH bulb to 400HPS Hortilux for flowering, but I think I can say; no major difference, yet. And I consider that a Good thing....

Now, for the hijack question?...for anybody cruising though.

I am thinking about putting the male in a separate room, and using the pollen to make seeds (one 1 female), for the future grows. At 2 feet tall and very healthy: what would the minimun light requirements be to keep it growing well enough to make pollen?

All input welcome....:thumbsup:

I guess I would have to go out and buy something; I only have 4 foot floro tubes now......and want to keep it to the minimun possible.

Hey Dutch how much heat is your lamp giving off? Is it aircooled? How far can you keep it from your plants?
